OEM fan belt

[bopperd]

I am looking for an original fan belt and sleeve C15840 for my car. I presume Lucas was the OEM but I don't know the Lucas number nor have I any idea what the sleeve looks like. Are there photos here somewhere?
Thanks,
Dave

Fan belts were made by John Bull I believe and were in a box like this Fiat example (although they would not have had the price sticker):


This example is from a Daimler:




I am still researching it but the Lucas catalogue for the E-Type makes no mention of a fan belt. I need to find a John Bull catalogue to figure out the part number.

Amazing, David. Simply amazing.

Yes, what he said. Where do you get all this stuff David?

If you think this would be of value to you, buy it and I will reimburse you for it. Better you should have it than me.

John Bull were a major supplier of rubber products and many children would wake on Christmas morning to find a John Bull Printing Set in their stocking. They made hoses, tyres, pedal rubbers, motorcycle hand grips, knee pads amongst other things and in 1958 became a subsidiary of Dunlop. John Bull also owned Metalastic Ltd. The fan belt catalogue looks like this but all we need is a scan or photo of the Jaguar section (belts and hoses etc).



As regards the 'spare' fan belt:


It is listed in the June 1963 J30 SPC but not in the August 1961 printing suggesting it was only included in the light of experience as witnessed by the above leaflet inserted into the Owners Handbook. It was introduced in June 1962 at engine number R5250. Basically if your Owners Handbook has the insert there should be a spare fan belt in the "luggage compartment". As regards any packaging my current thoughts are:

1. Jaguar would have pressed John Bull for the best possible price for the supply of 2,500 belts at a time. Neither John Bull nor Jaguar would have been bothered with individual packaging because winding the belt for insertion was time consuming and Jaguar would have had the waste disposal problem after fitting.

2. On the other hand, at the end of the production line, it may have been easier to throw in a boxed fan belt and the orange colour would have allowed the quality control people to easily spot it had been included. It would also reassure the owner.

3. I have not been able to find any extant John Bull boxes in an E-Type. However if a curious owner had looked inside the box and withdrawn the belt it would have sprung to shape and it is almost impossible to get it back in without tearing the cardboard (I tried!). Either they employed some very strong people to do it or used a machine. It is likely therefore the packaging got dumped.

4. As the spare belt was placed in the luggage compartment it is likely the new owner would have removed it to a place of safe keeping - e.g. a shelf in the garage.

I will continue to research the issue but if anyone finds out more please let me know because once we have a consensus I will include it in the Factory Fit thread - until then the packaging is only speculation.

David,
I will continue to look for the correct fan belt part number. Regarding the John Bull OEM hoses with the white "Made in England" stencils, was this marking evident on the hoses when the cars left the factory? I have not seen them anywhere on original cars.

No. The hoses fitted at the Factory did not have the white paint markings and the yellow/red stickers - again to reduce costs..

A bit more information on fan belts.

The early cars up to engine #R5249 (June 1962) used a single 'V' belt #C15840. From engine #R5250 a 'Duplex' belt #C19524 was adopted having twin 'V' tracks. The aluminium water pump pulley was replaced by a cast iron one which together with the dynamo, crankshaft and jockey pulley were modified to suit the new belt. So only cars built after June 1962 would have had a) the spare belt supplied in the luggage compartment and b) the red notice leaflet in the Owners Wallet.
